State of New Hampshire (Surficial Mapping)

The Project

The State of New Hampshire is creating a statewide coverage of surficial geologic maps as part of the NH STATEMAP program, which is funded jointly by the State of New Hampshire and the U.S. Geological Survey. EGGI was selected as the first-ever private contractor to participate in this geological mapping program.

Status/Results:

Over the last 12 years, EGGI scientists have conducted detailed geologic mapping to produce the surficial maps of thirteen 7.5 minute Quadrangles. In addition, EGGI developed and tested methods for using DEM and LANDSAT data to guide and supplement the field mapping. Surficial geologic maps of the Quadrangles were produced in digital format for use in the GRANIT GIS database and GRANIT website. EGGI was instrumental in developing standards for the maps with the office of the New Hampshire State Geologist, Dr. David Wunsch.

"John Brooks, Ph.D., P.G., (EGGI) has been contracted by the New Hampshire Geological Survey under my direction for the purpose of conducting surficial geological mapping for the State’s STATEMAP Geological Mapping Program. STATEMAP is a federal cooperative program that requires peer review of all funding proposals, completed maps, and associated geologic descriptions and data. In addition, the completion of these products is regulated by a stringent delivery timetable each year. Dr. Brooks has completed two maps over the past two years. Our mapping program requires a robust effort in data collection, compilation, and dissemination of the final product. Dr. Brooks, d.b.a. Emery & Garrett Groundwater, have performed admirably in this regard.”
